Compassion, empathy, self-sacrifice, sadness, joy, bloody mindedness with the tragi-comic pathos of the human condition thrown in for good measure, all this and more forms the backdrop to social worker Heather Thompson's remarkable friendship with old soldier Joe in the twilight of his life. This determined woman goes the extra mile, ably abetted by her supportive husband Nigel, to fill the void in 91 year-old Joe's life when his wife goes into a nursing home. A powerful bond develops as the story unfurls between the dependent old man and his dedicated carer.
